When I try to use <a href="http://docs.racket-lang.org/web-server-internal/web-server.html?q=do-not-return#(def._((lib._web-server/web-server..rkt)._do-not-return))">do-not-return</a> I get this error: <font face="courier new, monospace">bonsai.rkt:22:3: do-not-return: unbound identifier in module</font><div> <br></div><div>Then I tried <a href="http://docs.racket-lang.org/reference/Byte_and_String_Input.html?q=read-line&q=do-not-return#(def._((quote._~23~25kernel)._read-line))">read-line</a>, which worked, but it blocks the console output so I'll only see the things that my script is sending to the console after I hit Enter and finish the program. Is there a asynchronous way of doing this?<br> <div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Nov 12, 2012 at 1:55 AM, Greg Hendershott <span dir="ltr"><<a href="mailto:greghendershott@gmail.com" target="_blank">greghendershott@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">If I understand correctly you simply need your main Racket thread to<br> wait, for example, after your main thread calls your `start-server':<br> <br> (start-server)<br> (displayln "Server started.
